DAGVIZ offers a "git log"-like visualization for DAGs represented in networkx.
DAGVIZ can be installed with pip:
pip install dagvizDocumentation is available at https://wimyedema.github.io/dagviz/.
DAGVIZ relies on networkx for the representation and manipulation of the DAG. An SVG file can be generated as follows:
import dagviz
import networkx as nx
# Create the DAG
G = nx.DiGraph()
for i in range(5):
G.add_node(f"n{i}")
G.add_edge(f"n0", f"n1")
G.add_edge(f"n0", f"n2")
G.add_edge(f"n0", f"n4")
G.add_edge(f"n1", f"n3")
G.add_edge(f"n2", f"n3")
G.add_edge(f"n3", f"n4")
# Create an SVG as a string
r = dagviz.render_svg(G)
with open("simple.svg", "wt") as fs:
fs.write(r)
